Measuring Jitter Transfer

HOW TO: View the Results

1Choose the results FORMAT.

If GRAPH is chosen, a plot of the jitter transfer results against the ITU-T mask is displayed.

If TEXT is chosen, the results from which the graph is constructed are displayed: Point number, Frequency, Mask amplitude (dB), Jitter Gain (dB), Result.

If applicable, results 13 through 55 can be viewed on pages 2 through 5.

2If GRAPH is chosen, choose the SCALE required.

WIDE provides a vertical axis range of +5 to -60 dB and is recommended for viewing the high frequency portion of the graph. This allows a clearer view of the difference between the actual result and the ITU-T pass mask.

NARROW provides a vertical axis range of +3 to -3 dB and is

recommended for viewing the low frequency portion of the graph. This allows a clearer view of the difference between the actual result and the ITU-T pass mask.

3If you wish to log the jitter tolerance results to a printer, See “Logging Jitter Transfer Results” page 114.
